The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, I’ve gotta be straight with you – this is a tough stretch for Kennebunk Beach. The first week and a half is pretty much a write-off. We’re looking at a long gap of almost two weeks with nothing worth paddling out for. The swell is tiny, the wind is mostly messy, and the energy numbers are just sad. It’s not until the very end of the run that we finally see a pulse.
There’s one day that stands out, and it’s a long way off. On the morning of Saturday, the 22nd of August, we finally get something to talk about. The swell picks up to 4 ft from the SE with a solid 12-second period. The combined energy jumps to 356 (moderate), so there’s actual power behind it. The wind is light and cross-offshore from the east at 3 mph, which means the surface will be clean. It’s still only a “surfable” call, so keep expectations in check, but compared to the desert we’ve been looking at, this is the best on offer. The water temp is about average for the time of year.
The afternoon of the 22nd gets a bit windier and messy again, so that morning window is your only shot. After that, the 23rd has a bit more size but onshore winds ruin it. This is a sheltered spot, so it needs everything to line up, and for most of this run, it just doesn’t. Keep your eye on that Saturday morning, but don’t hold your breath too hard on the long-range – it’s promising but not locked in.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
